8. You are planning to use a ceramic tile design in your new bathroom. The tiles are blue-and-white equilateral triangles. You d
ira [324]

Step 1

Find the area of one equilateral triangle

Applying the law of sines

Area=\frac{1}{2} *a*b*sin C

in this problem

a=b=7 cm

C=60 degrees

so

Area=\frac{1}{2} *7*7*sin 60

Area=\frac{1}{2} *49*\frac{\sqrt{3}}{2}  \\ Area=49*\frac{\sqrt{3}}{4}cm²

Step 2

To calculate the area of the hexagon multiply the area of one equilateral triangle by 6

Area Hexagon=6*[49*\frac{\sqrt{3}}{4}]  \\ Area Hexagon=73.5*\sqrt{3}cm²

therefore

the answer is the option

73.5 sqrt 3cm²

P = nc - e and p is 4520 and n is 3000 and e is 700 what is the value of c
adoni [48]

Answer:

c= 1.74

Step-by-step explanation:

4520 = 3000(c)-700

4520=3000c-700

+700             +700

5220=3000c

c=1.74

to check to see if this is right you would do this:

4520=3000(1.74)-700

4520=5220-700

4520=4520
